Rising Mechanism Angles Display for Ergonomic Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices, such as slide phones, require users to change gestures or move the device to input on a keyboard while viewing the screen, as the display and keyboard remain parallel, limiting convenience.
Innovation Solution
A rising mechanism is integrated between the upper and lower bodies of the device, allowing them to form an angle when spread, enabling easier holding and viewing by sliding and rotating the upper body relative to the lower body, facilitated by a four-bar linkage and elastic members for semi-auto sliding functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display screen and keyboard remain in parallel stacking configuration, then the device volume is reduced, but the user convenience for inputting and viewing is deteriorated
Solution Approach 1:
The patent applies the dynamics principle by transforming the static parallel stacking configuration into a dynamic adjustable structure. The rising mechanism enables the display screen to transition from a fixed parallel position to an elevated angled position, allowing the device to adapt between compact storage mode and ergonomic usage mode. This resolves the contradiction by making the configuration changeable rather than fixed.
Solution Approach 2:
The patent implements dimensionality change by introducing vertical elevation through the rising mechanism. Instead of merely horizontal sliding, the display screen is lifted in the vertical dimension to form an angle with the keyboard. This adds a new spatial dimension to the interaction, enabling both compact stacking and ergonomic viewing angles to be achieved at different times.
2Ease of operation
If a rising mechanism is added to enable angled positioning, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The rising mechanism is segmented into distinct functional components: a rising module with linkage arms, guiding structures, and elastic members. This segmentation allows each component to perform a specific function (lifting, guiding, providing restoring force) and simplifies the overall design by breaking down the complex motion into manageable parts that can be manufactured and assembled independently.
Solution Approach 2:
The elastic members (springs) provide automatic restoring force that enables the rising mechanism to return to its initial position without external intervention. This self-service feature reduces the need for additional motors or actuators, simplifying the mechanism while maintaining bidirectional movement capability. The mechanism serves itself by using stored elastic energy to reverse the lifting action.
3Adaptability or versatility
If the first body slides and rotates relative to the second body, then the angled positioning is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The rising mechanism acts as an intermediary between the first body (display screen) and second body (keyboard). It mediates the complex sliding and rotating motions by providing guiding structures and linkage arms that constrain movement along predetermined paths. This intermediary structure translates user input into precise angular positioning without requiring direct high-precision manufacturing between the display and keyboard components.
Solution Approach 2:
The guiding structures and linkage arms are pre-configured during manufacturing to define the exact trajectory and angular relationship between the display screen and keyboard. By establishing these geometric relationships in advance through precision machining of the guiding features, the system achieves accurate positioning without requiring complex real-time control or post-assembly adjustments.

AI summary
A handheld electronic device including a first body, a second body, and a rising mechanism is provided. The second body is stacked under the first body. A side of the second body facing the first body has a depression. The rising mechanism is connected between the first body and the second body. The rising mechanism is slidably coupled to the first body, so that when the first body and the second body are relatively spread, the first body slides relative to the rising mechanism. In addition, when the first body reaches a predetermined position, an end of the first body enters the depression, the rising mechanism drives the first body to rotate relative to the second body, and an upper surface of the first body and an upper surface of the second body form an angle.
